Definitions

  • This invention relates to a safety electric lock with timed opening.
  • the remote controlled electric locks for gates or front doors of houses and buildings have the drawback to let the door or gate open when the remote control push button -usually placed within the house- is actuated by error or when the person to be let in does not cross the threshold and goes away without closing the door.
  • the remote control push button usually placed within the house- is actuated by error or when the person to be let in does not cross the threshold and goes away without closing the door.
  • the object of the present invention is to eliminate the above drawback by realizing an electric safety lock that can be opened by remote control, which does not require a manual intervention to be closed in case the remote opening command has been given by mistake, but on the contrary which allows for a completely automatic closure.
  • the object of the invention is that of realizing a lock of this type wherein the closing latch is not necessarily disengaged from the jamb due to the opening impulse, but is only unblocked, leaving the door openable through an easy manual intervention during a predetermined time interval following the opening impulse, after which the latch is blocked again and the door is locked in case it has not been manually thrown open.
  • a safety electric lock comprising a box having at least a side aperture for the passage of a latch adapted to engage a door jamb outside the lock and in a position corresponding thereto, characterized in that said latch is rotatably mounted about a vertical pivot and is urged to rotate by a spring, said pivot being fastened to a slide also urged by a spring, movable between a position in which said latch projects from said box aperture and a position in which said latch is substantially retracted, and a member adapted to block the rotation of said latch, actuated by an electromagnet controlled by a timer, said blocking member being maintained in a blocking position when the electromagnet is de-energized, and being brought into a blocking position during the time interval in which the electromagnet is energized, said time interval being defined by said timer.
  • the lock according to the invention is housed within a box 1 mounted on a (not shown) door in correspondence of the door jamb 2 which provides for a suitable cavity or recess 4.
  • Fig.s 1, 10 and 11 show the lock members that can be seen after removing the box side wall normally facing the inside of the door, so that the door opening is achieved through a movement by means of which the lock approaches the observer, as can be appreciated in Fig. 8 where the jamb is shown in perspective view behind the observer.
  • the structure 9 is a fork shaped member, fastened to the slide 8 through its transverse branch 11, and carrying a pivot 14 between its parallel branches 12, 12′, fitted in a through hole 18 of the latch 10 and provided with a head 19.
  • a helical spring 15 is interposed between the latch 10 and the pivot 14, having one end 16 introduced in a small hole 20 of the latch 10 (as can be seen in the plan view of Fig. 6), and the opposed end 16′ introduced in a similar small hole 20′ drilled in the head 19 of pivot 14, as can be seen in detail in Fig.
  • the helical spring 15 is a flexion spring that works as a torsion spring, i.e. is stressed to rotate the latch about the fixed pivot 14.
  • the rotation of the latch about the pivot 14 is further limited by the "torsion" of the spring 15 since the spring opposes the rotation during the opening phase, and restores the initial position after the opening, as will be explained later.
  • the load acting on spring 15 is adjusted by rotating the pivot 14 in respect of the latch 10 and by fixing the position thereof through the screw 21 whose stem 22 enters a cavity 23 of the head 19 of pivot 14.
  • a spring opposing the translation movement away from the jamb is subjected to the action of a spring opposing the translation movement away from the jamb, and urging on the contrary the movement toward the jamb.
  • a spring is a helical spring 26 housed in a cylindrical seat 27 formed in a guide sleeve 28 fastened to the slide 8 by means of its base 29.
  • One end of the spring 26 is fastened to a short push rod 30 projecting from the guide sleeve 28 and abutting against the side 3 of the box 1.
  • the translation movement of the slide 8 away from the jamb 2 causes the spring 26 being compressed against the push rod 30.
  • FIG.s 5-9 and 12-14 An embodiment of the latch 10 is schematically shown in Fig.s 5-9 and 12-14. According to this embodiment, it substantially consists of a cylindrical sector block having a hole or bore 18 housing the pivot 14 near the vertex, with a projection 35 abutting against the branch 11 of the fork supporting structure 9, so that the plane face 32 is about parallel to the bottom wall 5 of the box 1 when the projection 35 is abutting against the structure 9.
  • the cylindrical surface 33 extends between the plane face 32 and the projection 35, and a second plane face about orthogonal to the face 32, forms a pawl 38 with the projection 35.
  • a horizontal arm 42 terminated by a stop pin 44 extending downward and abutting - in the operative position corresponding to the non energized electromagnet - against the pawl 38 so as to prevent the rotation thereof.
  • the lower portion of the box 1 shown in detail in Fig. 4 houses a safety device for blocking the closed lock. It comprises a rod 50 with a rounded tip 51, a middle frusto­ conical portion 52 starting from a portion 65 and terminating with a portion 53 having a reduced diameter.
  • the rear portion 56 of the rod is housed in a cylindrical guide sleeve 55 fastened to the wall 3. Between the guide sleeve 55 and the wall 56 there is interposed a spring 54 urging the rod out from the box 1 through a hole drilled in a second cylindrical guide sleeve 59.
  • a double bend blocking lever 60 is pivotally mounted about a vertical pivot 61 fastened to the base wall 7 of the box 1.
  • a spring 63 urges the vertical portion 64 of the lever 60 against the rod 50, this latter being completely retracted within the box 1 in the arrangement of Fig. 1, with the tip 51 thereof pressed against the jamb 2.
  • the vertical branch 64 of the lever 60 is pressed against the portion 53 of reduced diameter of the rod, whereas the end portion 66 of the lever abuts against the lower projection 13 of the structure 9, thus blocking (preventing) the movement of the slide 8.
  • Fig. 1 shows the lock in the closed condition, it is understood that the blocking device just illustrated constitutes a mechanism that increases the safety of the closure against possible attempts of breaking open the lock, but does not constitute a mechanism necessary for the operation of the main members of the lock.
  • a timer 70 of known type connected to the electromagnet 40 by leads 71, 71′, and fed in a known manner by a low voltage.
  • the timer is actuated by a push button 74 remote from the door and placed, for example, within the house and usually associated to an intercommunication system.
  • Fig. 6 still shows the lock in the locked door condition corresponding to the situation of Fig. 1.
  • the latch 10 is introduced in the cavity 4 of the door jamb 2 with the plane surface 32 abutting against the jamb.
  • somebody has to come in and has been so allowed by the consent command which lifts the pin 44 he pushes the door as usual in the direction shown by arrow A in Fig. 6 - i.e. toward inside - thus causing the abutment of the surface 32 against the jamb 2 and, as a reaction, the rotation of the latch 10 about the pivot 14, as shown by arrow B in Fig. 7.
  • This rotation causes the spring 15 within the latch to be flexed.
  • the latch reaches the final position of Fig.
  • Fig. 1 and Fig. 10 only relate to the arrangement of the members of the safety blocking device and not the arrangement of the main members of the lock. Namely, during the opening, the outcoming of the rod 50 is preferably progressive, this being obtained by means of a curved shape of the jamb 2 - as shown in perspective in Fig. 10 - over which the rod tip 51 slides.
  • the vertical branch 64 of the lever 60 abuts against the portion 65 of larger diameter of the portion 53, so that the lever 60 is rotated with respect to the position of Fig.s 1 and 4, as shown in Fig. 11.
  • the closing is obtained by means of a translation movement of the assembly formed by the slide 8 and all the members fastened thereto, including the latch 10.
  • the closing is obtained by pushing the door against the jamb 2, along the direction of the arrow C in Fig. 12.
  • the cylindrical surface 33 of the latch 10 comes in conctact with the corresponding curved surface of the jamb 2 and consequentely causes a translation of the latch and of the slide fastened thereto through the blocking pin 44, backward along the direction of arrow D.
  • the translation continues with the further push of the latch against the jamb, as illustrated in Fig. 13, and reaches the maximum in the position of Fig. 14, corresponding to the elevation view of Fig. 15.
  • Fig. 16 shows how it is possible to obtain the manual opening of the lock by means of a key.
  • the eccentric portion 82 of the cam is carried by the key rotation to lift the bar 41 of the electromagnet and therefore to free the latch pawl 38 from the stop pin 44. It is thus possible to open the door without the intervention of the above described electric components.
